I even looked this up - google and read several.
Evidently, there is no actual difference other than
what different areas name them. Butter beans are just
lima beans. Butter beans tend to be a southern description.
Jill's can of butter beans comes from the south.

With the old-school country people here, butter beans
are merely overcooked limas (usually small ones so more
tender). Overcooked to make them more tender, then always
finished off with a lot of butter in the remaining bit
of water. Soft and buttery...butter beans.

Buy a bag of frozen limas and just heat them up or cook
for a short time and they are firm (like al dente) and
a bit mealy. I don't care for those. Cook them long and
slow then toss in butter = much better. Butter beans.
